Percutaneous extraction of a coiled, 20-year-old lead in a patient with cardiac resynchronization therapy.

A 61-year-old patient with a 20-year history of permanent pacemaker implantation and half--a-year cardiac resynchronization therapy using a left ventricular lead placed via surgical approach was admitted for extraction of an old coiled right ventricular lead, which triggered ventricular arrhythmia and created a risk of pulmonary embolism. The lead was extracted via the left femoral vein in two stages: untying a loop on the lead using a pig-tail catheter and Dotter basket followed by traction and dissection of adhesions using a Byrd dilator sheath. Dissection of the old lead from the active right ventricular one posed special technical problems.
